Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already disclose readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=true. The description adds useful scope information by saying the copy includes everything on the board and sub-boards, but it does not clarify what "as a template" means operationally or what side effects/permissions are involved.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The definition is a single front-loaded sentence with no wasted text. It efficiently communicates the core action and the key included scope.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple three-parameter mutation tool with full schema coverage and annotations, the description covers the main action and included content. However, it leaves ambiguity around what "as a template" means and does not mention the return value or confirmation behavior, which matters somewhat because there is no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so board_id, title, and parent_board_id are already documented in the schema. The description adds no parameter-specific semantics beyond the schema, which is the baseline expectation when schema coverage is complete.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: it copies a board, including everything on it and sub-boards. This clearly distinguishes duplication from creating a new empty board, though it does not explicitly name sibling alternatives such as create_board or export_board.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase "as a template" implies the intended use case, but the description does not explicitly say when to choose duplicate_board instead of create_board, export_board, or other board tools. Usage is therefore only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
